AssessPy is a software package for Python developed by the Cook County Assessor’s (CCAO) Data Department. It contains many of the functions necessary to perform a standard sales ratio study.
For assessors, we believe that this package will reduce the complexity of calculating ratio statistics and detecting sales chasing. We also hope that reporters, taxpayers, and members of academia will find this package helpful in monitoring the performance of local assessors and conducting research.
